Controlling your position is a prerequisite for stable profits. If you follow the trend, you can increase your position appropriately. If you go against the trend, you can reduce your position. How to make more profits in the right market and minimize losses when you are wrong is the strategy we need to deal with. Investment is to use small losses to compete for big profits. This is the best way to survive in this market, because even if you go against the trend, your entry point may not be very good. As long as the overall trend does not change, you can still make profits by taking the order, it's just a matter of time. However, if you take a counter trend order, once the situation changes, you are basically not far from losing more and more.
